What's in this directory?

These are files containing the installer and other software
for the Debian GNU/Linux operating system.
The files in this directory are specifically for
the amd64 architecture.

How do I use these files?

The files here are complete ISO images, ready to use.

Once you have downloaded all the ISO images you want, you will
typically need to write them to installation media.

What size and type of media will I need?

The images described here are sized to be written to
writeable Blu-Ray media
at a minimum, but may be written to larger media if needed.

For extra convenience, these images may also be written
directly to a USB stick. So long as your computer will
boot directly from that USB stick, it should start the Debian
installer that way.

There are lots of files here! Do I need all of them?

In most cases it is not necessary to download and
use all of these images to be able to install
Debian on your computer. Debian comes with a massive set of
software packages, hence why it takes so many disks for a
complete set. Most typical users only need a small subset of
those software packages.

Initially, you will only need to download and use
the first image of a set (labelled as
debian-something-1 to be able to start the
Debian installer and set up Debian on your computer. If there are
more images available here
(labelled debian-something-2,
debian-something-3, etc.), they contain the
extra packages that can be installed on a Debian system (as
mentioned previously). They will not be
bootable and are entirely optional. If you have a fast Internet
connection, you're most likely better off installing any
desired extra packages directly from the Debian mirrors on the
Internet instead of by using these extra images.

What is an edu BD image?

The edu BD here is a special version of
the BD image that is targeted specifically at 64-bit Intel machines.
It provides a menu to install the Debian Edu Pure Blend without the
need of an Internet connection. See the
Debian Wiki for
more information.

How can I verify my download is correct and exactly what has
been created by Debian?

There are files here (SHA512SUMS, etc.) which contain checksums
of the images. These checksum files are also signed - see the
matching .sign files. Once you've downloaded an image, you can
check:
